Association between systemic inflammatory response syndrome and hematoma expansion in intracerebral hemorrhage.

BACKGROUND

Hematoma expansion (HE) is a relatively common complication after intracerebral hemorrhage.

OBJECTIVES

To explore the association between systemic inflammatory response syndrome (SIRS) and HE in patients with intracerebral hemorrhage (ICH).

MATERIAL AND

METHODS

From June 2013 to October 2020, the sociodemographic data and clinical data of 780 ICH patients were collected. The logistic regression analysis with odd ratios (ORs) and 95% confidence intervals (95% CIs) was performed to analyze the risk factors for HE in patients with ICH.

RESULTS

Hematoma expansion occurred in 151 (19.36%) patients with ICH. Significant differences were presented between SIRS and HE (OR = 2.549, 95% CI: [1.497; 4.342], p = 0.0006). After adjusting the covariates, a further analysis showed that the respiratory rate >20 beats/min (OR = 3.436, 95% CI: [1.981; 5.960], p < 0.0001), white blood cell (WBC) > 12×109/L or WBC ≤ 4×109/L (OR = 2.489, 95% CI: [1.494; 4.149], p = 0.0005) increased the risk for HE in ICH patients. Our study also found that the significant differences between HE and non-HE patients in proportion of patients with history of diabetes mellitus, basal ganglia hemorrhage, hypothalamus hemorrhage and fasting blood glucose (all p < 0.05) (OR = 2.076, 95% CI: [1.274; 3.381], p = 0.0034), basal ganglia hemorrhage (OR = 2.512, 95% CI: [1.496; 4.218], p = 0.0005), hypothalamus hemorrhage (OR = 2.121, 95% CI: [1.007; 4.466], p = 0.0479), high C-reactive protein (CRP) (OR = 1.013, 95% CI: [1.002; 1.024], p = 0.0184), and hyperglycemia (OR = 1.099, 95% CI: [1.026; 1.178], p = 0.0074) were associated with an increased risk of HE in ICH patients.

CONCLUSIONS

The SIRS is closely associated with the risk of HE. Respiratory rate >20 beats/min and WBC count >12(109/L) or ≤4(109/L) increased the risk for HE in ICH patients. These findings can help to achieve the early prevention of HE and improve the prognosis of ICH patients.
